[GITLAB] - UPGRADE TO v12 on Wednesday the 18th of December at 11.30AM

Commit f33e9a70 authored by Cedric Roux's avatar Cedric Roux

do not exit immediately in case of busy thread

5ms by default, easy to change (change the 10 in the loops)

if the behavior is worse than before, do git revert [commit ID]
